Nitro benzanilide

Preferential reduction of a nitro group in the presence of a carbonyl group in 4-nitroacetophenone ISD, intramolecular rearrangements of o-nitro-benzanilides 32) intramolecular cyclizations of o-nitro-ferf-anilines to benzimidazol-1-oxides 153,154) cyclizations of acylated 2-nitrodiphenylamines to phenazine-l-oxides i ), intramolecular additions of nitro groups to double bonds 156) remarkably ef-... 

Die Photolyse einer sehr verdunnten, micellaren Losung von Benzanilid und seiner 4-Methyl- und 4-Nitro-Derivate in 0,01 molarem waBr. Natrium-dodecylsulfat fiihrt unter Fries-Verschiebung zur Bildung von 2-Amino- (80%), 2-Amino-5-methyl- (90%) bzw. 2-Amino-5-nitro-benzophenon (90%)l. 

Benzanilid 2,4-Dihydroxy- E5, 1049 (ArH + R-NCO) 1,2-Benzochinon 4-Anilino-5-methoxy- VII/3b, 106 Benzol 2-(a-IIydroxy-benzyl)-l-nitro- E21b, 1312 [Ar —CHO + H5C6-Ti(OR)3]... 

Nitration also takes place directly with the anilides (acetanilide or benzanilide), which may then be hydrolyzed yielding nitro aniline. In this case the para compound is obtained almost exclusively. 

The retention characteristics of 4,4 -disubsthuted benzanilides and benzamides (chloro, methyl, methoxy, nitro) were conducted on a Cjg column (2 = 254 nm) using a series of acetonitrile/water mobile phases [919]. The contribution of the substituent b> retention was tabulated and a predictive model for the calculation of log 2 values was presented. Mobile phase compositions from 35/65 to 70/30... 

More recently, one of us [56,212,213] started the routine synthesis of poly(p-benzanilide terephthalamide) (p-BT) and poly(/>-benzanilide nitro-terep-thalamide) (p-BNT) ...
